摘要
应用混合有限分析法拟合坐标系对粘性流体圆柱绕流进行了数值计算,得出Re<40形成的分离区长度和分离角同试验资料吻合很好。也计算了Re=100和200时,旋涡的形成和脱落,算得的脱落斯特罗哈数分别是0.16和0.19,同试验结果完全相符。
Hybrid Finite Analytic Method with the boundary fitted coordinate system is used to calculate the viscous flow past a circular cylinder. For the length of separation zone and the separation angle atRe < 40 the agreement between the calculated results and the experimental data is good. The flow patterns at Re-100 and Re = 200 are also calculated. It is concluded that the corresponding Strouhal numbers of the vortex shedding from cylinder are of 0. 16 and 0.19 which agree satisfactorily with the experimental results by Roshko.
